NAIL-DRIVING MACHINE.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed December 8, 1914. Serial No. 876,110.

To all whom it may concern:

Be it known that I, LEE E. RAINBOLT, a citizen of the United States, residing at Bedford, in the county of Lawrence and State of Indiana, have invented a new and useful Nail-Driving Machine, of which the following is a specification.

The present invention relates to improvements in nail driving machines, one object of the invention, being the provision of a machine that will drive a nail through a plurality of thicknesses of material, preferably paper bags, so that the nail may remain therein and thus hold the bags in position upon display racks as is the customary practice in grocery and other stores.

A further object of the present invention, is the provision of a nail driving machine of this character, in which the bags'to receive the nail are normally held in a compact or compressed position during the initial driving of the nail, the grip for'holding the nail being a sectional grip, so that when the hammer for finally driving the same is operated, the sectional gripping member will be opened to permit of the proper release of the nail and the final driving thereof.

A still further object of the invention, is the provision of a machine of this character which is exceedingly -simple in construction and operation, and therefore efficient and practical in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a side elevation of the complete implement with the parts in the position they normally assume. Fig. 2 is a front elevation thereof. Fig. 3 is a view similar to Fig.1 taken from the 0pposite side of the machine; Fig. 4 is an enlarged front elevation of the lower part of the machine showing the driving member in its lowermost position with the nail clamp and holder in open position. Fig. 5 is a detailed sectional view taken through the nail clamp andholder. Fig. 6 is a detail view showing a modified mounting for the guide.

Referring to the drawings, the numeral 1 designates the base, which has fixedly secured thereto the plate 2 which carries the upstanding paper guides 3, there being two of these guides, so that the aper, as for instance bags may beinserte thereagainst to properly receive the nail 17 which acts as a holding means when used in connection with the usual form of bag rack. Mounted adustably upon the base 2 between the guides 3 is the foot 4: which is adjustably held in place by means of the set screws 5. Formed integral'with the foot 1 is an upright 6, carrylng a forwardly extended open frame 7 at the upper end. Mounted in the frame 7 for vertical reciprocatory movement, is the stem or rod 8, which has mounted thereupon with- 1n the frame 7 the spring 9. This spring normally exerts a tension downwardly upon a pm 10 carried by the rod 8, so as to hold downv the member 11 carried by the rod. Thus a presser foot 12 carried by rod 8 will be pressed downwardly to resiliently hold and compress a stack of bags (not shown) therebeneath. The presser foot 12 is provided near its center with the nail guiding slot 13 so that the nail 17, as clearly illustrated in Fig. 4:, will be guided therethrough and finally into the alined slots 2 and 1 of the respective base members 2 and 1. These slots also permit the bags, with the attached nail, to be moved forwardly from beneath the presser foot.

Connected to the front face of the member 11 above the presser foot 12 by means of plvot screws 14, are the laterally swing- 1ng members 15, which are socketed as at 16 for the reception of the nail 17, there being provided the rod 18 which is loosely mountedin both of the pivoted members so that the respectlve springs 19 carried thereby will hold the members 15 toward each other thus to properly grip the nail 17 therebetween, whereby, upon the initial movement of the member 11 downwardly, the point of the nail will be projected through the slot 13 and into the bags a sufficient distance to permit the nail to stand aloneduring the final operation ofthe present device.

In order toprovide a means for elevating the member 8, and cause the presser foot 12 and the nail guide member 15 to assume the position as shown in Fig. 3, there is pivoted at one side of the machine at 20, the operating handle 21, said handle 21 being provided with a cam 22 which rides beneath one end of the pin 10 thus to elevate rod 8 against the action of the spring 9. Thus it will be necessary to move the lever 21 from the position shown in Fig. 3 to that shown in Fig. 1, to permit the presser foot 12 to be lowered in resilient engagement with the pack of bags after a nail has been inserted between the members 15 with the point thereof below the presser foot 12.

Mounted for vertical sliding movement within the frame 7 and parallel to the stem or member 8, is the driving member 23, which is provided with the head 24, that constitutes a blow receiving member, but which may, if desired, be operably connected to a foot treadle so that the member 23 may be actuated thereby. The lower reduced end 25 of the member 23 constitutes the driving portion thereof. Thus when the member 15 with the nail therein is lowered, as shown in Fig. 1, the member 25 will be co-axial with the upper end of the nail 17 so that when the same is driven from the position as shown in Fig. 2 to the position as shown in Fig. 4, the head of the nail will be primarily engaged with the lower end of the member 23 and will thus be driven practically the full distanceof the jaws or members 15 before the enlarged portion of the member 23 engages the jaws to separate them and thus free the said jaws from the nail.

The tensions of the springs 18 are such as to normally grip the nail between the members 15 with suflicient pressure to permit when the spring 9 is released and the presser foot 12 is lowered to cause the point of a nail to be driven through a sufficient thickness of the bags to be maintained in a vertical position and started before receiving the final blow from the member 25 when the rod 28 is driven, either by the hand, hammer or by foot power as may be found desirable. Or the clamp may hold the nail during the complete driving operation, the clamp being operated simultaneously with the final setting of the nail.

Carried upon one side of the frame or support 6 is a nail receptacle 26.

In the construction shown in Fig. 6, the member 4 is held rigidly upon the base 1 while the base 2 is adjustable, this being the reverse of the structure heretofore described.

It will thus be seen that by adjusting the foot 4 in the construction shown in Fig. 1 through Fig. 4, that the position of the presser foot 12 relatively to the guides 3 will be changed, so that the nail may be driven at various distances from the edge of the bag, while in the construction shown in Fig. 6, the guides are adjustable and the frame remains fixed at all times.
